Can be an ex or jealous aquaintance or colleague or just as easily someone who has only crossed your path online, on Facebook.

Their behaviour can include:

1. Unwelcome private messages until you block them.
2. Following you around from group to group to read and respond to your posts, as they can no longer message you.
3. Cloning you.
4. Creating fake accounts to try and befriend you and get access to your profile that way - failing that: to harass you.
5. Starting up hate groups about you.

A Facespook will sometimes try to pass off their abusive and harassing behaviour as "trolling" to other members of a shared Facebook group, so that the victim is left to fend for herself.

types: "OMG I can't believe Mark started up a hate group about you! WHAT is up with that?!?! Talk about a Facespook! LMFAO"

A common complaint of celebrities and wannabes, a megraine is a severe headache caused by incessantly talking about oneself and focusing on one's problems without ever stopping to consider how fortunate one is and how other people have genuine problems.

Though not a serious medical issue, a megraine can cause sufferers to be incapable of functioning normally or permorming routine tasks for themselves - like wiping their own arse.
